Viual Acuity Tetability in African-American and Hipanic Children: The Multi-Ethnic Pediatric Eye Dieae tudy Original Reearch Article

Purpoe To compare the age- and gender-pecific tetability rate for the Amblyopia Treatment tudy (AT) HOTV viual acuity teting protocol uing the electronic viual acuity (EVA) teter in African-American and Hipanic prechool children. Deign Population-baed, cro-ectional tudy. Method Meaurement of preenting monocular ditance viual acuity uing the AT HOTV protocol wa attempted in all African-American and Hipanic children aged 30 to 72 month from the population-baed Multi-Ethnic Pediatric Eye Dieae tudy (MEPED). Children able to be teted monocularly in both eye were conidered able. Age-, gender-, and ethnicity-pecific tetability rate were calculated. Comparion of tetability among different group were performed uing Chi-quare analye and the Cochran trend tet. Reult Teting wa attempted on 3,126 children (1,471 African-American, 1,655 Hipanic; 50% female). Overall, 84% (83% African-American, 85% Hipanic; 86% female, 82% male) were tetable. Older children were more likely to complete teting uccefully than younger children (P < .0001). Age-pecific tetability in children 30 to 36 month of age, 37 to 48 month of age, 49 to 60 month of age, and 61 to 72 month of age wa 39%, 84%, 98%, and 100%, repectively. After tratifying by age, there were no ethnicity-related difference in children tetable (P = .12). Girl (86%) were lightly more likely to be tetable than boy (82%; P > .003). Concluion Monocular threhold viual acuity teting uing the AT HOTV protocol on the EVA teter (Jaeb Center for Health Reearch, Tampa, Florida, UA) can be completed by mot African-American and Hipanic prechool children, particularly thoe older than 36 month of age. Thi protocol therefore may be ued in minority prechool children a an integral part of the diagnoi and management of amblyopia and other form of viual impairment.
